The M/S Norrona is an another way to reach Iceland apart from the flights. If scenery is your main interest, except for a few views of mountains near Faroe Islands and Seydisfjordur, the Smyril Line journey from Denmark to East Iceland is not that interesting. After a while, I got a little bored of the ocean. It is a good option if you want to take your motorcycles or cars from Denmark for self-drive tour in Iceland.
